Before using the chain block, check carefully to check whether the rotating part is flexible, whether there is card chain phenomenon, whether the chain is short-circuited and cracked, whether the brake is safe and reliable, whether the pin is firm, and whether the cross bracket-mounted beam is solid and stable. Qualified to use
In use, check whether the lifting chain is twisted. If you have a big girl, you can use it after adjusting it.
In use, the first pull back the bracelet, the lifting chain to send, so that there is enough lifting distance of the inverted chain, pay attention to the operation gradually close, so that the chain gradually force, check no exception, before the formal operation
In the lifting operation, strict use of overloaded, regardless of the position in use, the zipper should be consistent with the direction of the sprocket to prevent the zipper bracket. Zipper use force should be even, not too fast too fast, when used in the horizontal direction, should support the chain in the fine chain of the population to prevent failure.
During the use of the inverted chain, the number of zippers should be determined according to the size of the chain lifting capacity. When the zipper is pulled, the reason should be ascertained. The number of zippers must not be increased or the jerkiness of the chain must be increased.
